I'm not sure. This burn was done with Roxio Easy Media Creator v7.0 and is certainly good! I've since uninstalled Nero since I haven't been using it much due to the fact that I think it's become a bit of a resource hog. I do have NeroVision Express installed yet though since I do use that program and like it - glad that application runs by itself without any issues from what I can tell.
And no - I didn't install the Drag To Disc portion of Roxio since that I guess is the portion that used to be DirectCD. Try to save myself as many headaches as I possibly can. So far I'm rather impressed with the Roxio suite of software.
